[0054] A wrist wearable knife (WK) according to an embodiment of the present invention as a wrist wearable knife for wearing on a wrist of a user through a wrist strap (not illustrated) includes a sheath body 100 and a blade body 200 as illustrated in FIGS. 1 to 10. Hereinafter, each component will be described in detail with continued reference to FIGS. 1 to 10.
[0055] The sheath body 100 is a component for accommodating the blade body 200 as illustrated in FIGS. 1, 3 and 4. The sheath body 100 may be attached to or detached from a wrist strap (not illustrated) such as a watch strap or a bracelet so that the sheath body 100 is always worn on the wrist of the user when the wrist strap is worn.
[0056] The blade body 200 is a component that is directly used for cutting, slicing, and shaving objects. As illustrated in FIGS. 1, 3 and 4, the blade body 200 may be detachably provided on the sheath body 100.
[0057] Thus, since these components are provided, the sheath body 100 may be worn on the wrist of the user through a wrist strap (not illustrated), and the blade body 200 may be removed from the sheath body 100, and a blade 201 of the blade body 200 may be used, and after use, the blade body 200 may be mounted on the sheath body 100 again, and ultimately may be kept worn on the wrist at all times, so the wrist wearable knife may be used as a survival item when the user is in distress or in an emergency situation, not only in the mountains or the sea as well as everyday life.
[0058] In addition, the wrist wearable knife (WK) according to an embodiment of the present invention may further include a wrist strap detachable portion 300 as illustrated in FIGS. 2 to 4. The wrist strap detachable portion 300 may detach (mounted or remove) the sheath body 100 with respect to the wrist strap.
[0059] Specifically, as illustrated in FIGS. 2 to 4, the wrist strap detachable portion 300 may include a wrist contact portion 310, a spacer connection portion 320, and a wrist strap through-hole 330. The wrist contact portion 310 may be provided to be spaced apart from the surface of the sheath body 100 facing the wrist of the user (a lower surface of the sheath body 100 based on FIG. 2). The spacer connection portion 320 may connect the wrist contact portion 310 to one side of the sheath body 100 in a spaced state. The wrist strap through-hole 330 forms a separation space between the sheath body 100 and the wrist contact portion 310 and may detachably pass the wrist strap (not illustrated). Therefore, the wrist wearable knife (WK) of the present invention may be easily and quickly detached (mounted on or removed from) with respect to the wrist strap by pulling the wrist strap through the wrist strap through-hole 330.
[0060] Moreover, the wrist strap detachable unit 300 may further include a wrist strap pressing portion 340 as illustrated in FIGS. 2 to 4. The wrist strap pressing portion 340 may apply a fixing force to the wrist strap in a state where the wrist strap (not illustrated) passes through the wrist strap through-hole 330.
[0061] Specifically, as illustrated in FIG. 3, the wrist strap pressing portion 340 may protrude convexly from the sheath body 100 toward the wrist contact portion 310, and elastically press and fix the wrist strap (not illustrated) that passes through the wrist strap through-hole 330. Furthermore, as shown in FIG. 3, the wrist strap pressing portion 340 may have one end provided in a cantilever shape on the sheath body 100 and its center may be bent convexly toward the wrist contact portion 310. Therefore, as the wrist strap pressing portion 340 is provided in the cantilevered shape, the wrist strap pressing portion 340 may be elastically supported by the sheath body 100, and the wrist strap pressing portion 340 is pressed and has restoration force while the blade body 200 is mounted on the wrist strap (not illustrated), and the blade body 200 may be firmly fixed to the wrist strap by the restoration force of the wrist strap pressing portion 340.
[0062] In addition, the wrist worn knife (WK) according to the embodiment of the present invention may further include a blade body detachable portion 400 as illustrated in FIGS. 1, and 3 to 9. The blade body attachable portion 400 may allow the blade body 200 to be detachably provided in the sheath body 100.
[0063] Specifically, the blade body attachable portion 400 may include left and right blade body accommodating portions 410 and blade body fitting portions 420 as illustrated in FIGS. 1 and 3 to 5. The left and right blade body accommodating portions 410 may be provided at both edges of the sheath body 100, respectively, and may surround and accommodate both circumferential surfaces of the blade body 200. The blade body fitting portion 420 may detachably fit the blade body 200 into the left and right blade body accommodating portions 410. Therefore, the sheath body 100 may be smoothly accommodated in the blade body 200 through the left and right blade body accommodating portions 410, and the sheath body 200 may be detached with respect to the blade body 200 by fitting the blade body 200 into the left and right blade body accommodating portions 410 through the blade body fitting portions 420, and in particular, since the fitting method is taken, it is possible to further increase stability by preventing the blade body 200 from sliding from the sheath body 100.
[0064] For example, as illustrated in FIGS. 1 and 3 to 7, the blade body fitting portion 420 may include a blade body guide inclined surface 421, a blade body support portion 422, and a blade body catching portion 423. As illustrated in FIG. 7, the blade guide inclined surface 421 may be formed on the front of the upper surface of the sheath body 100, and while the blade body 200 is inserted between the left and right blade body accommodating portions 410, may obliquely guide the blade body 200 to the front of the sheath body 100. As illustrated in FIGS. 6 and 7, the blade body support portion 422 may be connected across the front end of each of the left and right blade body accommodating portions 410, and when the rear part of the blade body 200 guided to the blade body guide inclined surface 421 is pressed from the top to the bottom, the front part of the blade body 200 is supported at the top to prevent the front part of the blade body 200 from rising upward. As illustrated in FIGS. 1, 3, and 8, the blade body upper catching portion 423 may be provided at the rear end of each of the left and right blade body accommodating portions 410, and when the rear part of the blade body 200 is pressed from the top to the bottom, inserted and caught with the blade body 200.
[0065] Therefore, while the blade body 200 is inserted between the left and right blade body accommodating portions 410, the blade body 200 may be guided obliquely to the front part of the sheath body 100 through the blade guide inclined surface 421, and when the blade body is guided to the blade body guide inclined surface 421, and then the rear part of the blade body 200 is pressed from the top to the bottom, the pressing force may be fully applied to the rear part of the blade body 200 while the blade body support portion 422 supports the front part of the blade body 200, and the blade body 200 may be inserted and caught in the blade body upper catching portion 423 while the rear part of the blade body 200 is pressed from the top the bottom by the pressing force.
[0066] Furthermore, each of the left and right blade body accommodating portions 410 may be elastically supported by the sheath body 100. Therefore, while the blade body 200 is inserted into the blade body upper catching portion 423, the left and right blade body accommodating portions 410 may be smoothly widened to the left and right.
[0067] In addition, the blade body fitting portion 420 may further include a blade body rear catching portion 424 as illustrated in FIGS. 5, 8, and 9. The blade body rear catching portion 424 may be provided at the rear end of each of the left and right blade body accommodating portions 410 and may prevent the blade body 200 from falling backward while being caught by the blade body upper catching portion 423. Therefore, it is possible to prevent the blade body 200 from falling backward while the blade body 200 is caught in the blade body upper catching portion 423, so that the blade 201 of the blade body 200 may be handled more safely.
[0068] Furthermore, the blade body fitting portion 420 may further include a finger insertion portion 425 as illustrated in FIGS. 8 and 9. The finger insertion portion 425 may be formed between the rear ends of the left and right blade body accommodating portions 410 and may have an open shape for inserting a finger to lift the rear end of the blade body 200.
[0069] In addition, the blade body fitting portion 420 may further include a drain hole 426 as illustrated in FIGS. 1 and 4 to 7. The drain hole 426 may be formed between the blade body support portion 422 and the sheath body 100, and may discharge water flowing into the end of the blade body guide inclined surface 421.
[0070] In addition, the blade body fitting portion 420 may further include a plurality of removal anti-slip protrusions 427 as illustrated in FIG. 5. The removal anti-slip protrusion 427 may be provided at the front part of the blade body 200, and when the blade body 200 is removed, may prevent the finger from sliding while the front part of the blade body 200 is pressed with the other one finger by lifting the rear part of the blade body 200 with any one finger through the finger insertion portion 425. For reference, the removal anti-slip protrusion 427 is illustrated only in FIG. 5 to be illustrated in the drawing.
[0071] In addition, the wrist wearable knife (WK) according to the embodiment of the present invention may further include a grip portion 500 as illustrated in FIGS. 5, 6, and 10. The grip portion 500 may be provided in the blade body 200 and increase the grip sense of the blade body 200 while using the blade body 200.
[0072] Specifically, the grip portion 500 may include a gripping hole 510 and a plurality of main grip protrusions 520 as illustrated in FIGS. 5, 6, and 10. The gripping hole 510 may be opened at the center of the blade body 200 and may hold a position where a thumb (not illustrated) and a middle finger (not illustrated) of a wearer face each other. Each of the main grip protrusions 520 may be formed along the inner circumferential surface of the gripping hole 510 and may prevent the thumb and the middle finger facing each other from slipping. For example, the gripping hole 510 may be opened in a substantially rectangular shape. Therefore, it is possible to hold the position where the thumb and the middle finger face each other with respect to the blade body 200 through the gripping hole 510, and the slipping of the thumb and the middle finger facing each other may be prevented through the plurality of main grip protrusions 520, thereby increasing the grip sense.
[0073] Furthermore, the grip portion 500 may further include a plurality of auxiliary grip protrusions 530 as illustrated in FIGS. 5 and 10. Each of these auxiliary grip protrusions 530 may be provided at the front part of one side circumferential surface of the blade body 200 and may prevent slipping when the wearer's index finger (not illustrated) touches them. Therefore, even if the index finger presses the front part of one side circumferential surface of the blade body 200 through the plurality of auxiliary grip projections 530, it is possible to prevent the index finger from slipping, thereby increasing the grip sense along with the plurality of main grip projections 520. For reference, referring to FIGS. 5 and 10, the blade 201 may be provided at the front of the circumferential surface of the other side of the blade body 200.
[0074] In addition, the wrist wearable knife (WK) according to the embodiment of the present invention may further include a finger support portion 600 as illustrated in FIGS. 4 and 7. The finger support portion 600 may protrude on the upper surface of the sheath body 100 to correspond to the gripping hole 510. Therefore, while lifting the blade body 200 with one finger so that the blade body 200 is smoothly separated from the sheath body 100 when the blade body 200 is removed, the pressing force may be applied to the sheath body 100 through the finger support portion 600 with the other one finger.
[0075] On the other hand, the wrist strap detachable portion 300 and the blade body detachable portion 400 (excluding the removal anti-slip protrusion 427) and the finger support portion 600 may form one body with the sheath body 100, and the grip portion 500 may form one body with the blade body 200.
[0076] While this invention has been described in connection with what is presently considered to be practical example embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
